Symbol Hz. The SI unit of frequency equal to one cycle per second. It is named after Heinrich Hertz.
Mathematics
The SI unit of frequency, abbreviated to ‘Hz’, equivalent to s–1. It is commonly used to measure the frequency of cycles or oscillations.
Astronomy
The unit of frequency. One hertz is the frequency of a cyclical event having a period of one second. It is named after the German physicist Heinrich Rudolf Hertz (1857–94).
Chemistry
The SI unit of frequency equal to one cycle per second. It is named after Heinrich Hertz.
Chemical Engineering
The SI unit of frequency where one hertz is equal to one cycle per second. It is named after German physicist Heinrich Rudolf Hertz (1857–94) who discovered radio waves.
Computer
The SI unit of frequency. A periodic phenomenon has a frequency of one hertz if each cycle of the phenomenon repeats itself in a period of one second. A megahertz (MHz) is one million (106) hertz; a gigahertz (GHz) is 1000 million (109) hertz.
Internet
The unit used to measure frequency, named after the German physicist Heinrich Hertz. It is usually abbreviated to Hz.
Biology
Symbol Hz. The SI unit of frequency equal to one cycle per second. It is named after Heinrich Hertz (1857–94), a German physicist.
